Identity Theft and Tax Refund Fraud

At the Minnesota Department of Revenue, we take protecting your personal information and tax refund very seriously. We verify the information on every return to make sure the right refund goes to the right person.

What is identity theft?

Identity theft occurs when your personal information (such as name, Social Security number, or banking information) is taken without permission and used to commit crimes or fraud, including filing a fraudulent tax return. Criminals can steal your personal information online, by phone, or by email.

What is the department doing to prevent refund fraud?

We take the time to make sure the right refund goes to the right customer by reviewing and verifying information on all tax returns. For more information, see our frequently asked questions on tax refund fraud.

Although software vendors transmit your return to us, we determine the validity of the return they submit. We may review or adjust your return even if you purchase audit protection from them.
